This paper explores in depth the nature of the conditional moment restrictions implied by log-linear intertemporal capital asset pricing models (ICAPMs) and shows that the generalized instrumental variables (GMM) estimators of these models (as typically implemented in practice) are inefficient....

This paper investigates empirically a model of aggregate consumption andleisure decisions in which goods and leisure provide services over time. Theimplied time non-separability of preferences introduces an endogenous source ofdynamics which affects both the co-movements in aggregate...
